Auction prices skew lower than retail because most lots have damage, salvage titles, or are dealer-only liquidations sold as-is with no warranty.

Prices reflect live Copart and IAAI sale data from the last 180 days. They are most useful for: gauging salvage rebuild margins, comparing private-party asking prices to the auction floor, and spotting overpriced dealer listings. For a clean-title retail estimate use the depreciation calculator.
